Kachi-Kachi Kacchin Clapper (DL-06)

For (With Whom)

People with hand paralysis who have difficulty clapping or cheering People with speech impairments who have difficulty using their voice

Why

The user has quadriplegia from a traffic accident and also has a tracheostomy. One day, they were to take part in a school event (sports day) and asked whether there was a way to cheer in their own way. Taking the user's condition into account, we thought about whether there was something they could use to express support.

How

First we visited the home and checked the user's physical condition. Because their fingers can fit around an object about the size of a baseball bat or tennis racket grip, we looked for something that would make a sound by swinging the arm while supporting the grip. After discussion with the user's reactions, their family and the helper staff in charge, it took its present form (hold the grip and swing it to make a sound). It is built so that when swung, a protrusion on the side strikes a protrusion on the body. Using PLA also produces a high-pitched sound.

Outcome

Although caregiver support is needed, the user was able to cheer by making sound with the Kachi-Kachi Kacchin. Because they could cheer in their own way whenever they wanted, they enjoyed the school event (sports day). They could also cheer on their friends, which deepened connections with others and helped build community.
